The given table is to be completed by determining the formula, type (ionic, molecular or acid) and name of the given compound. Concept Introduction: Ionic compounds are formed between the metals and non-metals. The naming of ionic compounds which contains a metal forming only one type of ion is as follows: name of the cation (metal) + base name of anion(nonmetal) + − ide The compounds which are composed of non-metals are known as molecular compounds. The molecular compounds are named by writing the name of first element with the prefix. This is followed by the prefix of second element and suffix ‘-ide’ is placed on the end of the name of second element. The prefixes are written to indicate the number of atoms present in the compound. Oxyacids are the combination of one or more hydrogen ions with an oxyanion. The naming of these acids depends on the ending of the oxyanion. The naming of oxyacids ending with –ate is as follows: First base name of oxyanion is written followed by the suffix –ic to it and then, the word acid follows it.

Interpretation Introduction

Interpretation:

The given table is to be completed by determining the formula, type (ionic, molecular or acid) and name of the given compound.

Concept Introduction:

Ionic compounds are formed between the metals and non-metals.

The naming of ionic compounds which contains a metal forming only one type of ion is as follows:

name of the cation (metal)+base name of anion(nonmetal)+−ide

The compounds which are composed of non-metals are known as molecular compounds. The molecular compounds are named by writing the name of first element with the prefix. This is followed by the prefix of second element and suffix ‘-ide’ is placed on the end of the name of second element. The prefixes are written to indicate the number of atoms present in the compound.

Oxyacids are the combination of one or more hydrogen ions with an oxyanion. The naming of these acids depends on the ending of the oxyanion. The naming of oxyacids ending with –ate is as follows:

First base name of oxyanion is written followed by the suffix –ic to it and then, the word acid follows it.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments. This especially applies to the reactions in…
